π Info: Stale python-jose type stubs remain
python-jose was dropped from runtime dependencies, but types-python-jose still appears in both dev dependency lists. These stubs are now unused after the PyJWT migration.

π‘ JWT clock-skew tolerance silently disabled
The 60-second clock-skew tolerance is passed inside the PyJWT options dict (leeway at auth.py), but PyJWT only reads leeway as a top-level decode() argument and ignores it inside options, so tolerance defaults to zero. Tokens are rejected the instant they expire and just-issued tokens fail whenever the login server's clock runs slightly ahead.

π Info: crit header rejects every token that carries it
The validation loop unconditionally raises on the first item, so any token with a crit header is rejected regardless of value. This matches the intent of supporting no critical extensions, but the per-item isinstance check never runs past the first element.

PyJWT 2.13.0 source jwt/api_jws.py PyJWK algorithm_name decode key PyJWK
π‘ Result:
In PyJWT 2.13.0, significant changes were made to how PyJWK objects and their algorithm_name property interact with the jwt.decode() process, primarily to address a security vulnerability (GHSA-jq35-7prp-9v3f) where the JWT header's alg could bypass the caller's allowed algorithm list [1][2][3][4]. Key details regarding jwt/api_jws.py and PyJWK in version 2.13.0 include: 1. Binding Algorithm Names: During signature verification, PyJWT now explicitly binds the JWT header's alg to the PyJWK.algorithm_name [2][3]. This ensures that when a PyJWK (or PyJWKClient) is used as a key, the algorithm specified in the token header must match the algorithm associated with the JWK, preventing attackers from bypassing the algorithms=[...] allow-list [4]. 2. Security Fix (Algorithm Allow-list Bypass): In previous versions (2.9.0 through 2.12.1), if a PyJWK was provided, the library would default to verifying with the PyJWK's fixed internal algorithm [4]. If the user did not explicitly provide an allow-list, or if the logic failed to check the header against the list correctly, the verification could be misled [4]. PyJWT 2.13.0 mandates that the token's alg is checked against the allow-list, and if a mismatch occurs with the PyJWK's algorithm, an InvalidAlgorithmError is raised [1][4]. 3. PyJWK Properties: The PyJWK class maintains an algorithm_name property [5] and an Algorithm property [6]. The algorithm_name is determined at construction time, either from the JWK's alg field or default key-type settings [4]. 4. Decoding Logic in api_jws.py: The decode() method now calls decode_complete(), which orchestrates these checks. When a PyJWK object is passed, the verification process confirms that the header algorithm matches the PyJWK.algorithm_name [7][4]. This update is a breaking change for applications that previously relied on a mismatch between the token's header alg and the PyJWK's algorithm, as these will now fail [1].

site:github.com/jpadilla/pyjwt/blob/2.13.0 jwt/api_jwk.py PyJWK from_dict algorithm_name api_jws _verify_signature
π‘ Result:
In PyJWT, PyJWK is a class defined in jwt/api_jwk.py used to represent a JSON Web Key (JWK) [1]. The from_dict static method is a factory that creates a PyJWK instance from a dictionary containing JWK data [1]. When a PyJWK instance is initialized, it determines the associated algorithm (bound to the self.algorithm_name attribute) based on either an explicitly provided algorithm argument or, if not specified, by inspecting the alg field within the provided JWK data [1]. The interaction between PyJWK and the signature verification process in jwt/api_jws.py was the subject of a security fix (GHSA-jq35-7prp-9v3f) included in PyJWT 2.13.0 [2][3]. Previously, when decoding a JWT using a PyJWK object, the signature verification logic in _verify_signature would use the algorithm bound to the PyJWK instance regardless of the algorithm specified in the JWT header, potentially allowing a bypass of the caller's algorithm allow-list [3]. To address this, the logic was updated to bind the JWT header alg to the PyJWK.algorithm_name during verification [2][4]. In the current implementation of _verify_signature in jwt/api_jws.py, if the key provided is an instance of PyJWK, the verification process now explicitly checks if the algorithm from the JWT header (alg) matches the algorithm bound to the PyJWK instance (key.algorithm_name) [5]. If they do not match, an InvalidAlgorithmError is raised, ensuring that the verification behavior remains consistent with the expected algorithm [5][3].

PyJWT 2.13.0 api_jws.py _verify_signature key PyJWK algorithm_name source
π‘ Result:
In PyJWT 2.13.0, the _verify_signature method in jwt/api_jws.py was updated to improve security regarding the use of PyJWK objects [1][2]. Specifically, the update prevents an algorithm allow-list bypass that existed in previous versions [3][4]. When a PyJWK object is used as a key for signature verification, the _verify_signature method now explicitly checks that the algorithm specified in the JWT header (alg) matches the algorithm_name bound to the PyJWK object [5][6]. If they do not match, the method raises an InvalidAlgorithmError [5][6]. The relevant logic within _verify_signature in PyJWT 2.13.0 is as follows: 1. Algorithm Selection: If the provided key is an instance of PyJWK and no explicit algorithms list is provided by the caller, the algorithm allow-list defaults to [key.algorithm_name] [5][6]. 2. Header Validation: The alg from the JWT header is checked against the allow-list (which may be the caller-provided list or the defaulted PyJWK algorithm) [5][6]. 3. Key Binding Enforcement: If the key is a PyJWK, the implementation enforces that the token's alg must match key.algorithm_name [5][6]: if alg!= key.algorithm_name: raise InvalidAlgorithmError( f"Token algorithm {alg!r} does not match the key's " f"algorithm {key.algorithm_name!r}") This change ensures that when using PyJWK or PyJWKClient, the actual algorithm used for verification is strictly bound to the key object, preventing tokens from potentially circumventing allow-lists by specifying a different algorithm in their header [3][2]. This fix was bundled as part of the 2.13.0 release to address the security advisory GHSA-jq35-7prp-9v3f [1][4][2].

PyJWT 2.13.0 api_jwt.py decode leeway options leeway source
π‘ Result:
In PyJWT 2.13.0, the leeway parameter is used to provide a time margin to account for clock skew when validating time-based claims, specifically 'exp' (expiration) and 'nbf' (not before) [1][2]. In the source code (jwt/api_jwt.py), the leeway parameter is defined as a float or datetime.timedelta [3]. When passed to the jwt.decode function, it is used within the _validate_claims method to adjust the timing checks [3][4]. If a datetime.timedelta instance is provided, it is converted to total seconds using.total_seconds [3][4]. Key details regarding its usage include: 1. Functionality: - For 'exp': It allows the token to remain valid for a small period after the expiration time has passed, helping to avoid rejection due to minor clock differences [1][2]. - For 'nbf': It allows the token to be validated even if the 'nbf' time is slightly in the future [1][2]. 2. Implementation: - The leeway is applied in the _validate_exp and _validate_nbf internal methods by comparing the token claim against the current time (now) adjusted by the leeway [4]. - The default value for leeway is 0 [5][6][7]. You can pass leeway directly to the jwt.decode call as a keyword argument [1][6]. Example: decoded = jwt.decode(token, "secret", leeway=5, algorithms=["HS256"]) # Alternatively, using timedelta decoded = jwt.decode(token, "secret", leeway=datetime.timedelta(seconds=5), algorithms=["HS256"])
